Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. is a shrub that belongs to the family Asteraceae and is native to Kenya. It is commonly known as the Kenyan everlasting and has gained popularity as an ornamental plant. In order to have a healthy and thriving plant, specific growth conditions must be met.
Light Requirements
The Kenyan everlasting thrives well under full sun exposure. It requires at least six hours of direct sunlight each day for optimal growth and development. If it is grown under partial shade or in places with low light intensity, the plant tends to become leggy and distort in shape.
Temperature Requirements
Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. is a heat-loving plant and grows best in warm to hot temperatures. The ideal temperature range for this plant is between 20°C to 30°C. It cannot tolerate extremely low temperatures and is susceptible to frost damage which causes leaf spot, leaf drop, and plant death.
Soil Requirements
The Kenyan everlasting prefers well-draining soils that are rich in organic matter. It grows best in slightly acidic to neutral soils. The soil must be moist but not waterlogged to prevent root rot. The addition of sand, clay, or loam can improve soil texture and drainage. The plant is also sensitive to soil nutrients and requires regular fertilization with balanced nutrients to support its growth and flowering.
Cultivation methods
Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. is a perennial herb that grows well in well-draining, fertile soils with a pH range of 6.5 to 7.5. The plant is tolerant of partial shade but grows best in full sunlight. It should be planted in an area that receives at least 6 hours of direct sunlight each day. The plant can be propagated through seeds or cuttings. Seeds should be sown directly into the soil after all frost has passed. Cuttings should be taken in the early summer and placed in well-draining soil.Watering needs
Proper watering of Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. is essential for its growth and survival. The plant needs to be watered regularly during the growing season, and the soil should be kept moist but not waterlogged. Watering should be reduced during the winter months, as the plant goes through a period of dormancy.Fertilization
Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. is not a heavy feeder and does not require frequent fertilization. However, a slow-release fertilizer with a balanced NPK ratio can be applied once a year during the growing season to promote healthy growth. Additionally, adding organic matter to the soil can help improve fertility.Pruning
Pruning Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. is not necessary, but it can help promote bushier growth and a fuller shape. Deadheading spent flowers throughout the growing season can also help promote continuous blooming. It is recommended to prune in the early spring before new growth emerges. Any damaged or diseased branches should be removed immediately to prevent the spread of disease.Propagation of Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr.
The Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. plant can be propagated in several ways:
Seed propagation
Seeds of Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. can be collected from the plant and used for propagation. Sow the seeds in pots or trays filled with a soilless mix. The seeds take 2-4 weeks to germinate. Keep the soil moist, but not waterlogged. Once the seedlings have grown to a suitable size, transplant them to their permanent location.
Cutting propagation
Cuttings can be taken from Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. Cut a stem from the mother plant just below the node, and remove all the leaves except for the top two. Dip the cut end in rooting hormone and plant it in a soilless mix. Keep the soil moist and place the cutting in a well-lit area. After several weeks, the cutting will root and can be transplanted to its permanent location.
Division propagation
Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. can also be propagated through division. Divide the mature plant by carefully digging it up and separating its roots and stems into several sections. Replant the divided sections into their permanent location, ensuring they are well-watered and in a well-lit area.
Propagation of Helichrysum stuhlmannii O.Hoffm. var. keniense R.E.Fr. can be done through seed, cutting, or division. Each method has its advantages and disadvantages, and the best one to choose will depend on the grower's preferences and circumstances.
